I've heard enough of this terrorists stuff on the radio & TV talk

just on radio alone.  It now seems almost all the experts investigating
this field say that it is only a matter of time when a terrorist
imports a nuclear bomb or dirty bomb into the U.S. or other countries
and lights it off.  What about NMR?  After studying it a little it
seems very possible to build a sensitive machine that can detect
uranium and other atoms.  I have no idea what materials they can use
for an effective nuclear bomb.  How difficult would it be to build such
a machine where the individual stands on a certain spot and the machine
scans for any atoms such as uranium?  According to a NMR table, Uranium
receptivity is about a million times less than hydrogen.  I guess that
means the EM signal from uranium is about a million times weaker than
hydrogen.  Is it still possible if the electronics is sensitive enough?
 Perhaps if the device is inside a shielded area such as a faraday
cage.

Any thoughts are greatly appreciated ... especially if it's your child
or grand child that your input might one day help save from a nuclear
fall out.

  What makes you think that there would be a chance to "NMR" the device
  *before* the perpetrator "lights it off"?
